# Post and Cable Spacing

**Post spacing (typical)**\
For aluminum or steel post systems, plan on putting your posts 4 feet (48 inches) apart on center. Tighter spacing limits cable deflection (bending) and simplifies tensioning but isn’t necessary.

**Wood systems**\
Use a structural (load-bearing) wood post every 8 feet with intermediate posts 4 feet between structural posts.

**Cable spacing**\
3-1/8″ on center through posts helps maintain compliance with the 4-inch sphere rule when correctly tensioned.
